To all whom it may concern:

Be it known that ll, Wimmer/r Gr. Corr, Va citizen of the United States, residing at Cleveland, in' the county of JCuyahoga and State of Ghia, have invented certain new and .useful Improvements in an AutomobilelBumper, of which the following isa specification. v y

'lhis invention .consists of a bumper or bud'er adapted to bei conveniently attached to either end of any automobile in general use. lt is constructed of separate pieces of spring steel formed and united together in a particular way so as to provide a strong and durable lspring assembly adapted .to den within limits to absorb and relieve heavy shocks and blows and avoid damage to the bumper and vehicle,"`and one ofthe pieces is in the form of a dat plate secured upon the front face of a straight bumper bar so as to provide a relatively wider impact area at the middle of the bumper than at its ends. l am aware that it is not broadly new to use aiseparate ltage-plate atthe middle of a spring bumper to provide a wider impact area at that point than at the ends, and therefore disclaim such a construction in view of the disclosures in the prior Vllrench patent of M. Slrrzydlewslri, No. 457,970, dated July 25, 1913. However, theconstruction and organization of parts as hereinafter shown and described and more particularly pointed out in the claims provides an exceptionally simple and eective form of bumper which in its specic form is new and novell in so far as l' am aware and can be manu f factured and supplied to the public at a comparatively lower cost than the bumper shownv in said French patent. Now, referring to the drawing accompanying this application, Figure l is a. plan or top view of my improved bumper in full lines, the end portion of an automobile being shown in dotted lines. Fig. 2 is a front or face view of 'the bumper. bumper comprises three pieces of spring l metal, to wit, a rear bar 2, a front bar 3, and

a face-plate Ll, respectively. Rear bar 2 is a straight vnarrow piece of metal excepting midway thereof where it is bent abruptly into arcuate shape of relatively short radius to vprovide a small-protruding bow portion 5 adapted to engage and reinforce the middle straight portion of front bar 3 which has its opposite ends 6 curved rearwardly and ea:-

lSpecification ot Letters Patent.

As shown, the

tending inwardly toward each other ,for a short distance into overlapping relation with the dat extremities of the long straight ends of rear bar 2. rllhree bolts or rivets 7 are used to secure bars 2 and 3 together vwhere engaged at their middle and at their respect1ve overlapping ends, and the middle Patented Nov. t5, dtml. .1. application niet september e, rear. sei-iai no. leases.

or portion 8 vof the plate is integral with the upper and lower impact sections itl-l0',

' that is to say that sections lO-lO are adapted to receive impacts without breaking or bending because of the integral connection 8 which crosses and is backed up bythe straight middle portion of front bar 3. Web

8 being integral with the plate, it also follows that the connection between the upper and lower impact sections lO-l() cannot become separated or loose as might occur" with a separate tiemember such asdisclosed in the French patent hereinbefore referred to.

The outlines and proportions of vthe plate l are subject to considerable variation but' the ends of the plate are preferably narrowed or reduced in width to approximately the width of fronti bar 3 and fastened by bolts or rivets l-l-ll to said bar 3, or these dll ends could be electrically welded or brazed i to the bar or fastened together in any other lrnown mechanical way. rllhe unionl of the rear and front bars and the face-plate at their middle makes the bumper erceptionally strong at this central point, and the short bow portion 5 permits an effective bracing union of this lrind to be made without materially impairing the resiliency and cushioning qualities ofthe bumper, and such a union also prevents independent vibratory movements and rattle of the bars where spaced apart. A short bow portion inrear bar 2. also affords relatively long straight spring ends adapted to be engaged and held.l adjustably in brackets secured tothe frame ofy the vehicle and whereby the bumper may be mounted onl frames oil different widths on brackets Vspaced apart diiderent distances'o Face-plate 4 may be of any suitable thickness -and in practice itis stamped or eut from a-slngie piece ot sheet-steel.

What I claim, isi- A' spring bumper or buffer for an auto-` mobile, comprising a straight front-bar having its opposite ends curved rearwardly and extending inwardly toward each other, and. a rear bar having straight ends affixed to the extremities of said front bar and formed with an abrupt arcuate portion of relatively small radius protruding forwardly at its middle adapted to engage the back side o said front bar midway between its ends.v

Q. A spring bumper or butter for an automobile, comprising separate front and rear bars spaced apart and connected together at their corresponding ends, and an open faceplate of greater width than said front bar having an integral connecting web at its center bearing against said front bar.

3. A spring bumper or buier tor an automobile, comprisinga rear bar and "a front bar united together at their corresponding ends but spaced apart between said ends and the rear bar having an arched portion at its middle engaging said front bar at its middle, an open tace-plate ot greater width than said front bar having an integral web at its middle bearing against said front bar', and means uniting said plateA and trent bar together.

d. A spring bumper or buffer for an auto-` mobile, comprising a rear bar having straight ends and an abrupt arcuate protrud ing portion at its middle, a straight front bar having curved ends bent rearwardly and inwardly toward each other in overlapping engagement with the ends of Said rear bar, a siottedface-plate having a middle web bearing against said front bar, means uniting the ends of said bars together, and means adapted to secure the arcuate portion of the rear bar and the web of said face-plate upon `opposite sides of saidiront han ln testimony whereof I aiiix my signature.
